NewEast Biosciences pioneered the research and development of the antibodies for GTPases and mutated Oncogene ten years ago. GTPases involve (1) signal transduction in response to activation of cell surface receptors, including transmembrane receptors such as those mediating taste, smell and vision, (2) protein biosynthesis at the ribosome, (3) regulation of cell differentiation, proliferation, division and movement, (4) translocation of proteins through membranes, (5) transport of vesicles within the cell, and vesicle-mediated secretion and uptake, through GTPase control of vesicle coat assembly. An oncogene is a gene that has the potential to cause cancer.
We offer three unique categories of antibodies, which (1) recognize only the active configuration of GTPase (not the inactive one), (2) mutated Oncogene (not mild type) and (3) have super affinity for cAMP and cGMP (no acetylation required). We have over one thousand peer reviewed articles cited our products.

Cat.#: 11546 |
Product Name: Human SPARC Protein |
Size : 10 µg, 50 µg and 100 µg |
Synonyms: BM-40;Osteonectin;ON |
Target: SPARC |
UNIPROT ID: P09486 |
Description: Recombinant human SPARC protein with N-terminal human Fc tag |
Background: This gene encodes a cysteine-rich acidic matrix-associated protein. The encoded protein is required for the collagen in bone to become calcified but is also involved in extracellular matrix synthesis and promotion of changes to cell shape. The gene product has been associated with tumor suppression but has also been correlated with metastasis based on changes to cell shape which can promote tumor cell invasion. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jun 2015] |
Species/Host: HEK293 |
Molecular Weight: The protein has a predicted molecular mass of 58.8 kDa after removal of the signal peptide. The apparent molecular mass of hFc-SPARC is approximately 55-70 kDa due to glycosylation. |
Molecular Characterization: hFc(Glu99-Ala330) SPARC(Ala18-Ile303) |
Purity: The purity of the protein is greater than 95% as determined by SDS-PAGE and Coomassie blue staining. |
Formulation & Reconstitution: Lyophilized from nanodisc solubilization buffer (20 mM Tris-HCl, 150 mM NaCl, pH 8.0). Normally 5% – 8% trehalose is added as protectants before lyophilization. |
Storage & Shipping: Store at -20°C to -80°C for 12 months in lyophilized form. After reconstitution, if not intended for use within a month, aliquot and store at -80°C (Avoid repeated freezing and thawing). Lyophilized proteins are shipped at ambient temperature. |
